Imperial Master of the Ming Dynasty

Zhuo Jing's cloudy eyes stared unblinkingly at Jiang Xinghuo's clear and handsome face.

Jiang Xinghuo drew a △ pattern on the ground with a tree branch, but the triangle was slightly flat.

"Make a metal instrument called a 'torsion scale', and then hang it up with a very tough metal wire. Tie a small polished mirror in the middle, preferably a glass mirror. If it doesn't work, you can use a better copper mirror. Okay, finally put the same small shot put on the left and right."

"Then use light, such as candlelight or sunlight, and look in the mirror. The light will be reflected to a far away place, and then immediately reflect the light to where the spot appears."

Jiang Xinghuo took out the Ba Si Ba Wen silver coin that Li Jinglong left for him from his sleeve.

The silver coin faced the sun and indeed refracted the light to the ground in the distance.

"What is the purpose of this little friend?" Zhuo Jing asked immediately.

Jiang Xinghuo continued to hold the silver coin and said: "The purpose of this is that due to the lack of mass between objects, the universal gravitation that exists between objects is extremely weak and extremely difficult to be observed by human eyes."

"But the light is different."

Jiang Xinghuo explained slowly: "As long as there is even a slight change in the very flexible metal wire that is tied to the mirror, the light that originally stayed in a certain position will travel far away in an instant."

"The next step is to place two identical shot put but with much larger mass at equal positions measured with a ruler. The two shot put need to be close to each other but not touching each other."

"And if gravity exists, then the attraction between the shot balls will inevitably cause the 'torsion balance' of this triangle to shift slightly."

"And as long as the 'torsion scale' shifts, even if it is very weak, and only moves a tiny bit, the very tough metal wire will also shift with the mirror, and the light refracted by the mirror will also shift. It will move a larger distance."

After listening to Jiang Xinghuo's explanation, Zheng He and Old Man Zhuo didn't say anything yet, but Zhu Gaoxu was the first to raise a question.

This Tiehanhan's intelligence has obviously improved a lot after being trained by Jiang Xinghuo.

"Mr. Jiang, how can we eliminate other interference? What I mean is that this gravitational force is caused by the mutual attraction between shot balls, not anything else, such as wind or human power."

"Oh, by the way." Zhu Gaoxu patted his head and said, "There are also changes in hot and cold. Mr. Jiang also said before that the air pressure is high in cold places and low in hot places."

Hearing these words, Jiang Xinghuo looked at Zhu Gaoxu silently.

For a moment, I was actually a little moved.

With sincerity, gold and stone can be opened, rotten wood can be carved, and with time and effort, an iron pestle can be ground into a needle.

The messy descriptions briefly rolled through Jiang Xinghuo's mind.

To sum it up, there are only two words, gratifying.

The stupid apprentice finally became smart.

Jiang Xinghuo continued.

"If you have a way, just create a secret room, open a small window and look outside."

"As for how to place the big shot put, you can use bamboo, wood, metal, etc. to make a slide rail and throw it in from the outside."

"Then light a candle in the secret room. In a darker place, it is easier to observe the movement of light."

After listening, Old Man Zhuo was silent for a few breaths, but then sighed.

"This method of proof is indeed feasible, but unfortunately it requires too many things and cannot be seen in the prison."

Zhu Gaoxu just said he wanted to see it today, but Zheng He, who was sitting next to him, pulled him without leaving any trace.

Zhu Gaoxu immediately realized that Zheng He had something to say.

In fact, this was indeed the case, because after Dao Yan found Zhuo Jing that day, he asked the jailer to pull Zheng He out to talk.

And it was that conversation that made Zheng He know Dao Yan's intention.

Why did Dao Yan go out of his way to find Zhuo Jing?

Of course, it's not because Zhuo Jing was the minister of the Jianwen Dynasty, but because in the era before Xie Jin, when Dao Yan and Yuan Gong were in their thirties, Zhuo Jing was already a great talent known all over the world.

With the passage of time, Zhuo Jing's literary reputation became more and more prosperous, and he was a man of mixed knowledge and broad-minded thinking. He was by no means a corrupt scholar who had read stupidly.

Therefore, Dao Yan believes that if you want to fight against Cheng Zhu Neo-Confucianism, Zhuo Jing may be a good helper.

After all, if Jiang Sheng had to do many things personally, it would be too low-level.

When the two armies are facing each other, how can the enemy's general come to call for battle, and our general has to take action personally because he has no one under his command?

The various quarrels between a few people under the new crooked neck tree are naturally not understandable to outsiders.

But in the secret room, the atmosphere changed a bit at this time.

——————

"Go and tell Commander Ji Gang to come over."

Zhu Gaochi's face was as serious as ever.

After hearing the instructions from His Highness the First Prince, the two clerks Guo Jing and Chai Che looked at each other. Chai Che got up and went to look for the person, while Guo Jing stayed in his seat.

Guo Jing could clearly see that the eldest prince Zhu Gaochi's expression at this time was as if the rag was about to be squeezed out of water.

It’s not that Guo Jing lacks knowledge and can’t describe it, but that this description is already the description that is closest to the actual situation.

On the chubby face of the eldest prince Zhu Gaochi, as he lowered his head, the flesh sagged significantly under the action of gravity. The layers overlapped each other, and the sweat and oil mixed together, making his face bright. to shine.

Soon, Master Ji Gangji, the commander of the Jin Yiwei, walked in with quick little steps like a frightened kitten.

Ji Gang had obviously not recovered from the painful experience of failing to build the wall. He looked at the eavesdropping and amplifying wall that had been in disrepair for a long time, with a look of helplessness in his eyes.

Ji Gang has already decided that if His Highness the First Prince still insists on letting him repair this broken wall that cannot be repaired at all, he will simply make it clear and say that it will be over if it cannot be repaired.

After all, although he took the blame for this incident, the root cause was not with him.

The craftsmen who built the wall and repaired it were all buried alive by Zhu Yuanzhang. What ability did Ji Gang have to repair it?

But unexpectedly, the movement on the other side of the wall came over the next moment.

Ji Gang breathed a sigh of relief, but almost instantly, Ji Gang's eyes widened.

The eavesdropping loudspeaker wall is working again. What is the eldest prince looking for?

Soon, Zhu Gaochi cleared up his doubts.

Zhu Gaochi told Ji Gang exactly what he heard from across the wall and what was needed for the experiment, as well as the principles of the experiment.

"Go, prepare now, we will see the results today."

Once Zhu Gaochi decided to do something, Ji Gang certainly couldn't stop him.

So Ji Gang left the secret room through the narrow passage with full of doubts and went to prepare materials.

In the secret room, Zhu Gaochi and the two clerks fell silent.

After a long while, Zhu Gaochi finally said leisurely: "Today's events are recorded on paper, but no one asks you, so just pretend you don't know. Do you understand?"

Guo Jing and Chai Che's hearts trembled.

The two of them replied in succession: "Understood!"

The reason why Zhu Gaochi said this was because in principle, Zhu Gaochi could not and did not dare to deceive his father, so the two clerks had to write down what was said across the wall on paper.

But writing it down on paper does not mean that the emperor will definitely see it, nor does it mean that the emperor will definitely understand it.

This is why Zhu Gaochi is protective of Jiang Xinghuo.

If Zhu Di had seen it, there would be nothing to say, but if Zhu Di, who had left at the beginning, had not seen it, or could not understand it, then naturally a lot of twists and turns would have been avoided.

After all, things like heliocentric theory and universal gravitation have a big impact on the theory of "induction between heaven and man".

There is no doubt about this.

Since Emperor Wu of the Han Dynasty deposed hundreds of schools of thought and only respected Confucianism, the set of things "response between heaven and man" has been the foundation for maintaining imperial power. Therefore, if Jiang Xinghuo cannot come up with a set of things that can also maintain imperial power in the heliocentric theory, .

Then when Zhu Di saw it, the best reaction would be disapproval, and the worst reaction no one could say for sure.

But no matter what, Zhu Gaochi still had to do this experiment.

Because Zhu Gaochi also had doubts about whether universal gravity existed.

If it didn't exist, then presumably it wouldn't have any impact on the imperial power.

——————

Unfortunately, Zhu Gaochi's stupid Ou Doudou didn't react until Jiang Xinghuo finished talking about it.

Zhu Gaoxu suddenly asked in hindsight: "Mr. Jiang, if the heliocentric theory is true and universal gravity exists, does it mean that the induction of heaven and man will not be true?"

As soon as these words came out, there was a brief silence under the Xinwanneck tree.

Old Man Zhuo looked at Yan Ni's number one thug with great interest. He had actually made such progress. Although it was a bit of hindsight, Wu Fu could realize this and understand this very sensitive issue. It’s really not easy.

Zheng He scratched his long beard irritably, what a fool like Zhu Gaoxu.

However, Zheng He was embarrassed in the next moment.

A small piece of the long beard that was glued on was scratched off, and what's worse is that this trend seems to be expanding.

As a last resort, Zheng He had no choice but to maintain this posture.

Fortunately, no one cared about him at this time, everyone was waiting for Jiang Xinghuo's answer.

And when Zhu Gaoxu said it, he also realized that the question he asked was not quite right.

After all, in Zhu Gaoxu's mind, two petty officials should be writing furiously next door at this time, faithfully recording their conversations.

These texts will be handed over to his father, Emperor Zhu Di.

Jiang Xinghuo nodded honestly.

"The heliocentric theory is established, universal gravity exists, and the interaction between heaven and man will naturally be self-defeating."

"Don't, stop talking."

Zhu Gaoxu suddenly began to hesitate.

Jiang Xinghuo instead smiled and said, "Is there anything I can't say?"

"The sun and the moon are for the sake of clarity."

As Jiang Xinghuo's meaningful words fell, everyone inside and outside the next door fell into thinking.

The so-called "I have a great Confucian to argue for me" is actually just like Dong Zhongshu's reform of Confucianism. It seems that if the heliocentric theory changes some of the interpretations, it does not mean that it cannot serve the imperial power of the Ming Dynasty.
